JOHN W. JACKSON, OF AMSTERDAM, NElV YORK,

SMOKE CONSUMER.

SPECIFICATION forming part of Letters Patent No. 695,155, dated March 1 1, 1902. Application filed February 2, 1901. Renewed February '7, 1902. serial No. 93,108. (No model.)

T0 aZZ whom it may concern:

Be it known that 1, JOHN W. JACKSON, a citizen of the United States of America, and a resident of the city of Amsterdam, county of Montgomery, State of New York, have invented certain new and useful Improvements in Smoke-Consumers, of which the following is a specification.

Myinvention relates to a device for consuming smoke in furnaces; and the object of my invention is to provide'a smoke-consumer so constructed that it maybe easily applied to a furnace and which will in its operation prevent smoke from being emitted from the smoke-stack, increasing and intensifying the heat in the furnace, and which will be inexpensive in its construction, simple in its operation, and which may be removed or attached to a furnace very quickly, together with such details as are hereinafterset forth and claimed. I obtain these objects by means of the mechanism illustrated in the accompanying drawings, in which Figure 1 is a perspective view; Fig. 2, a section; Fig. 3, an end elevation.

Similar letters refer to similar parts throu ghout the several views.

I am aware that heretofore smoke-consumers have been constructed in which an arrangement is made for conveying steam from the dome of the furnace through a pipe incased within a larger pipe, through which larger pipe air is conveyed to the furnace and emitted therein at a point adjacent to the delivery of the steam. I have found, however, that a more effective Sll] oke-consumer may be constructed when the air conveyed to the f urnace is mixed with the steam within a receptacle opening into the furnace and within which receptacle the heat of the furnace raises the mixture to a high temperature and which will when emitted into the furnace cause an immediate explosion of the gases arising therein, which will do away with the discharge of smoke. My invention therefore relates particularly to the construction of the receptacle in which the steam and air are mixed, together with the device for mixing the two within said receptacle.

Referring to the accompanying drawings, the cylinder A carries the air, also the steamagainst the sides of said nozzle, and to impinge upon the end of the removable nozzle G. The nozzle G is reinovably secured to the flaring nozzle F by the wings H, ears J, and

bolt K or in any suitable manner. With this arrangement it is apparent that the steam coming into nozzle F, together with the air entering therein through pipe 15, both the steam and the air being restricted in their passage therethrough by the removable nozzle G, will be thoroughly mixed and that this mixture will be discharged into the furnace through the opening in the removable nozzle G.

It is understood that the nozzle 1 and removable nozzle G project into the furnace. The nozzle G being submitted to intense heat is very likely to be burned off. By my arrangement when it is rendered unfit for use it can be readily replaced without cutting away the masonry forming the walls of the furnace or in any Way disturbing the furnace.

What I claim as my invention, and desire to secure by Letters Patent, is-

1. In a smoke-consumer, a nozzle having flaring sides, provided near its end with a removable nozzle, the interior wall of which extends into and forms an angle with the interior wall of said flaring nozzle, against which the steam and air passing through said nozzle will impinge; a means for removably securing said nozzles together; with a means for conveying steam and air into said flaring nozzle; substantially as described.

2. In a smoke-consumer, a miXing-ehamher; a pipe conveying air thereto; a pipe conveying steam thereto; said steam-conveying pipe enveloped by said air-conveying pipe; outwardly-flaring sides to said mixing-cham- ICQ ber extending throughoutapart of its length; ing sides and the parallel sides of said cham- 10 parallel sides to said mixing-chamber exber, substantially as described. tending throughout the remainder of its Signed at Amsterdam, New York, this 28th length; the diameter of the mixing-chamber day of December, 1900.
